Two cubes of volumes 8cm^3 and 27cm^3 are glued together at their faces to form a solid with the smallest possible surface area. What is the number of square centimeters in the surface area of the resulting solid? please help thank you
The answer is 76 cm^2. Hope this helps!
Smaller cube area = 24 cm2 (Area of a single side = 4 cm2)
Larger cube area = 54 cm2
Area of a solid = 78 - 8 = 70 cm2
